I mean Megan is 'there' a lot but she's really not that important in comparison to the turtles, she's there but not as important as the turtles.

The 2nd half of this movie should have been how the entire movie was because that's when the focus was 150% on the turtles. The build up is there before the turtles are revealed, then when they are revealed all [expletive] breaks loose and it does NOT stop lol the 2nd half of this movie is the best part of this movie.

I hope they improve upon that into the sequel. Which has been confirmed.
